我正在尝试升级 bash 以使其不易受到攻击。
我尝试了 Debian 的源列表生成器。但libtinfo5它阻止我升级 bash。我找不到旧版本（由于源列表问题）以libtinfo5查看是否可以安装它。

评论太长：
- 做
wget http://snapshot.debian.org/archive/debian-archive/20160313T130328Z/debian/pool/main/b/bash/bash_4.1-3%2Bdeb6u2_amd64.deb（假设amd64是你的架构） - 下载文件后，运行
dpkg -i bash_4.1-3+deb6u2_amd64.deb（以 root 身份/通过sudo）
严重地：升级此系统，或使其脱机。
